I still used dialog to take 4h. I'll probably try to shave more time off with dialog until I'm happy and then try for standard runs.
Here's a timed link for where I broke standard rules:

In standard you would have to take quest and then pull the reaper away instead of pulling and then dialoging the quest in aggro.
Definitely going to push further, there's at least 30 minutes more to shave off.
